Lyndon Howard Fuller was 22 when he vanished from Western Kings Memorial Hospital in Berwick, Nova Scotia, on the night of November 25, 1988. Admitted two days earlier after family concerns about mild depression, he became agitated that evening despite medication. He left the hospital around 6:30 p.m. and was escorted back about 40 minutes later.

At approximately 7:45 p.m. he jumped from a third-story window wearing only blue striped pajamas and no footwear. His father reached the landing, a nine-meter drop, but found only footprints in the grass and no sign of Lyndon; the night was clear and slightly below zero. No confirmed sighting has been reported since, and investigators and family have considered possibilities ranging from exposure to boarding a nearby train, starting a new life, or foul play.

What information might help resolve where Lyndon went that night?
